Recent Research Advancements in Metal-organic Frameworks for Radioiodine Adsorption
The foundation of nuclear medicine diagnosis and therapy is radioisotopes,such as 99Tc,131Ⅰ,137Cs,and 192Ir.However,the radioactive pollutants are inevitably produced during their production,storage,usage,and waste disposal steps.For example,131Ⅰ tends to accumulate and becomes concentrated in the thyroid gland,which can seriously affect human metabolic processes.Therefore,the safe disposal of the radioactive waste is desirable.This review summarizes the recent research advances of iodine adsorption over MOFs based on metal centers and provides a brief outline of the most prominent examples,including Cu-MOFs,Zn-MOFs,Co-MOFs,Zr-MOFs,Al-MOFs,Ni-MOFs,Th-MOFs and Cd-MOFs.In addition,the major challenges and prospects of the use of MOFs in handling radionuclide issues are also discussed.
